使用CSS / Javascript显示围绕球体的图像

我知道这可以通过three.js实现,但似乎three.js最大化了一个网格球体,并且图像有点失真。如果可能的话,我也宁愿使用CSS。

这可以通过CSS转换完成吗?理想情况下,我想将它从平面图像变为动画,这样可以通过CSS过渡轻松制作动画效果很棒。

我找到了一个很好的例子,说明如何在codepen上使用CSS:http://codepen.io/donovanh/pen/GBIiv。它实际上并没有将图像包装在3d中,但它看起来非常适合我的目的。

以下是相关的html / css:

<section class="stage">
  <figure class="ball"><span class="shadow"></span></figure>
</section>

.ball {
  display: inline-block;
  width: 100%;
  height: 100%;
  margin: 0;
  border-radius: 50%;
  position: relative;
  -webkit-transform-style: preserve-3d;
  background: url('https://alxgroup.net/gto-range-builder/images/treeSS.png') repeat-x;
  background-size: auto 100%;
  -webkit-animation: move-map 30s infinite linear;
  -moz-animation: move-map 30s infinite linear;
  -o-animation: move-map 30s infinite linear;
  -ms-animation: move-map 30s infinite linear;
  animation: move-map 30s infinite linear;
}

.ball:before {
  content: "";

  width: 100%;

}

.ball:after {
